How does it find peers? Same way core would?
I have released a unique privacy tool and code library that broadcasts Bitcoin transactions **directly** into the P2P network.
1. No external dependencies whatsoever.
2. No centralized backends.
3. Uses Tor if found running on the same system. Having the Tor Browser open in the background is enough.

The same way: DNS seeds with a fixed peer list for fallback.
